The Falcon™
Setting a New Corrosion Coupon Safety Standard

The Alternative

Setting a New Corrosion Coupon Safety Standard

The Falcon™ Ultrasonic (UT) probe (US Patent 10,345,221) is the safest corrosion coupon in the world. The Falcon UT probe requires no unnecessary corrosion coupon removal and eliminates the safety risks associated with the handling of traditional coupons. The Falcon UT probe includes a pre-weighed corrosion coupon that is analyzed directly or remotely by the customer with a PC-based software application. By measuring the direct changes in corrosion coupon thickness and mass loss of the corrosion coupon, the Falcon UT probe provides all the benefits of in-stream corrosion rate monitoring without the inherent safety risk of a traditional corrosion coupon.

BSI has designed these assemblies to fit any industry standard access fitting or NPT ball valve fitting. The Falcon Ultrasound probe is designed using rugged and durable components that withstand high pressures (up to 2,160 psi for retractable; higher psi available for drip pot assembly) and temperatures up to 500°F. Each UT probe has a single transducer working with a permanent coupling that provides precise thickness measurements of the corrosion coupon over time.

Proper Probe

Measure With
Unsurpassed Accuracy

Primarily used to measure external corrosion, BSI FalconTM  Ultrasonic Testing (UT) Probes are compatible with your existing pipe access fittings. Designed for both above and belowground tanks, buried piping, and other mechanical structures that necessitate monitoring, these powerful tools help to preserve and protect your infrastructure.

How UT Probes Work

Our "Smart" ultrasound probes amplify the capabilities and the value of the physical components found in traditional testing probes. BSI’s breakthrough technology in this area has literally reshaped the way our clients are able to acquire mechanical integrity data.

The design of the probes selected for a project will depend on monitoring location and conditions.


Monitoring Locations


Probes can be installed on standard access fittings. Utilizing proven and cost-effective technology, ultrasound waves are reflected from the front face of the metal surface to the "back wall" which provides a precise measurement of the wall thickness (after adjusting for the speed of sound in the material). The data from these measurements is tracked and trended in order to determine local or general wall loss. Installations and monitoring do not disrupt business operations.


UT Probes can be used underground, where they are buried next to the asset that needs to be monitored. If there is any type of discrepancy found in the corrosion coupon, this likely indicates cracks or other hidden internal flaws that require further examination. The data obtained can also be used to monitor the effectiveness of cathodic protection, and to mitigate the problem of soil-side corrosion.

UT Probe Applications

Built to measure coupon wall loss instantly through precise ultrasonic testing, our “Smart” probes can be used in many scenarios, including the following common applications:

Storage Tanks

Enable corrosion monitoring, remotely, from outside of the tank to evaluate the effectiveness of protection of the tank as well as the levels of any soil-side corrosion.

Under Insulation

Installed from above ground with no insulation removal, the BSI UT Probe can monitor corrosion 360° around the pipe.


Eliminate the need for coupon removal, cleaning, shipping, and weighing, while increasing corrosion rate intelligence.

The Ultrasound Difference

Historically, ultrasonic instruments have been used to evaluate the integrity of components manually. In many circumstances, the accuracy of these measurements is operator dependent.  In addition to being somewhat inconsistent and unreliable, manual assessment can be disruptive to operations, is time intensive, and costly. A more proven and predictive approach is to use the precision of ultrasound technology in a more automated fashion, eliminating variables that may impact measurement accuracy.

24-Hour Monitoring

BSI software collects, aggregates, cleanses and formats invaluable data for our customers every hour, 24 hours a day. With a rapid processing speed for collecting large data sets, SCOUT™ offers multiple interface options to support the most popular current databases and conventional data collection systems.

Easy to Interpret

The SCOUT™ interface, accessible online, incorporates unique display features for easy user interpretation and subsequent decision-making. It works with Windows, iOS, and Android. All software and hardware updates are included in the cost of your system.


Cognizant that different customers have different needs, BSI developed SCOUT™ to be fully customizable based on customer preferences. For example, users can control whether they would like a real-time or scheduled Cloud upload, or they can choose to set text or email alerts. Modifications to the interface itself can be made to respond to unique requirements.

Power Options

At BSI, we understand that not all applications are alike. Our UT Probes are designed for a variety of client-driven scenarios:

  • Compatibility with local 110/240 VAC power
  • Instrumentation DC power
  • Solar power/battery
  • Power over Ethernet (POE)

Data Interface

System users also have the option of taking measurements either manually or wirelessly. If done manually, data is captured and stored quickly in the field with BSI’s Universal Logger. There are no depth limitations or service interruptions for either option. Data can be accessed online through a secure interface at a later time.

Wireless technology has become the optimum method for transmission of asset management data in the petro chemical, energy generation, and mining industries. BSI partners with the leading communication carriers and wireless equipment providers to accommodate user response time expectations and data security requirements.

Why BSI?

BSI excels in translating the precision and reliability of ultrasound, previously only found in a laboratory setting, into real-world field environments.

Our engineers and scientists are experts in the development of unique, rugged ultrasound sensors and “Smart” probes as well as the design of signal processing software that enhances and preserves data quality.
